Answer 1

HI there,

The light will not clear on it's own right away with this code. This is because the car has to do a drive cycle or two to run it's own self tests. That being said, if it's still running poorly or giving you this code, check the fuel pressure and make sure that the catalytic converter isn't plugged. If it is, then you will get a lean code due to the exhaust blowing back into the engine.
